Ok, so after reading the attached doc, and going through a bunch of other bits trying to figure it all out. I'm probably re-stating the obvious for some but maybe helping others like myself who had no real fucking clue figure things out...
First: DMR isn't just an encapsulation in the same way P25 is, it's a whole new way of transmitting information (TDMA) this means, there's no possibility of using existing repeater infrastructure to cross over and support DMR.
Second: DMR end-user equipment isn't a be-all-end-all it needs a repeater infrastructure and a great deal of set-up to work.
I've been looking at the Radio Oddity GD-77: https://www.radioddity.com/radioddity-g ... r-mic.html
There are a few different packages and versions available from radiooddity depending on what it comes with, one comes with a programming cable, one with a speaker mic. From a radio perspective, it does support DMR, and encryption with DMR, however it also functions as an analog radio, and unlike most of the P25 units out there, is dual band.
At the moment anyways, moving over to DMR would require either: A) Buying in to the existing infrastructure - i.e. getting a radio ID, and etc from the DMR-MARC, and all the associated overhead, or B) anticipating the purchase of a DMR repeater system (import units seem to be about $1600-1800 and are not portable). I have seen a few people talk about building their own nano-repeaters, however most of these systems seem to transmit in the milliwatt range, which isn't really what most of us would be looking for. I'm not sure if there are any possibilities on the horizon for building smaller more portable units. One site I found listed the following for a "DMR Hot Spot":
On doing some further digging, it looks like for a local repeater setup (i.e. Not connected to DMR-MARC) you can use analog radios with a discriminator tap. This guy has a pretty good write-up on it:Raspberry Pi III Model B with Case : $52.00
DVMEGA UHF Board: $129.00
SMA Antenna : $10.00
Total Cost $219.99

I know most of the push so far has been towards using P25, however, this presents some very major hurdles for all of us in the relatively near future: High startup cost, relatively high maintenance costs (batteries, accessories, equipment), lack of frequency agility (this is an ongoing problem), lack of good organization (frequency allocation), and a host of other problems. At the moment, DMR may be a good solution for those of us left off the P25 bus.
